This breaks final link due to missing THREAD_SIZE definition in head.S:
LD vmlinux
arch/m68knommu/platform/coldfire/head.o: In function `_clear_bss':
(.head.text+0xa4): undefined reference to `THREAD_SIZE'
Without that asm-offsets.c change it works on my ColdFire boards.
I am happy with it:
With that, I get a duplicate reference to THREAD_SIZE. head.S should include
asm/thread_info.h rather than THREAD_SIZE being redefined in asm-offsets.

Yes, I get that too. I just hadn't tracked down why that was yet.
Unfortunately, I don't have a binutils that can handle the funny Coldfire
instructions. Can you point me at a Coldfire toolchain?
This is what I currently use:
http://www.uclinux.org/pub/uClinux/m68k-elf-tools/tools-20080626/m68k-uclinux-tools-20080626.sh
Its just a binutils-2.18 and gcc-4.2.4 configured for m68k-uclinux
target.
